To all whom 'it may concern.'

Be it known 'that l, .Devin l. BONE, a citizen ot the United States of Aniericaresiding at'Qgleshy, in the county of Coryell and State of Texas, have invented certain new and useful Improvements in ah Apparatus 'for Hydrating Lime, of which the tollowingis a specification. Y

My invention relates to an apparatus for producingn hydrated lime; and the object is to combine the means that are required and necessary in making a high grade hydrated lime; to provide a new, and improved conibination of apparatus for making hydrated lime whereby it may be burned and hydrated in a simple and economical manner and by the means of which a much purer linie can be made with' much less expense; and by dispensing;r with much of the machinery heretofore used in hydrating lime. (lther objects and advantages will he fully explained in the following, description and the invention will be more yparticularly pointed out in the claim.

Reference is had to the accompanying drawing-s which forni a part ot' this applicz tion.

Fig. l is a diagrammatic view, showing a hydrating linie plant. Fig. 2 is a vertical section ot' the linie elevating mechanism with a perspective View of a screen and bagging; machine. Fig'. 3 is a detail View of the car lowering and elevating means.

Similar characters of reference are used to indicate the same parts throughout the severa-l views.

-ln carrying,-v out the improved invention herein set forth, l use the heat producing de ficos shown in the patent granted to ine on Oct. l5, 1918, No. 1,281,902, `for burning These devices include a kiln l tor the linie., aq'furnace d tor burning h is ted thereto by striking devices i6, i8.. and 23. The furnace e' is provided with Trate 5, andtuel 14 tells through the fire zr l on the grate 5.' rlhe combustion is aided hy heated air which comes from a fire loo); l0. This lire box is provided with grate hars i2, doors l1 and 13, a, damper o1' valve 2d, line 8. and a tunnel-shaped discharge` 9. The heated air rises troni boi: l() up through the tuel is. The fuel -is thoroughly' consumed in the furnace 4 which produces great heat. rThe heat is directed tothe lime kiln or lime burning' furnace l intowhich the lime-in the raw state is fed. "The furnace 4 .for the tram cars 27.

)Hand the steam are detained in the is duplicated with all its working parts as shown on both sides of the kiln. After the linie is burned thoroughly, it passes down through the discharge hopper or outlet 60 which is provided `with gates or slides 2G so that the burned linie can be dumped into small train cars 27. Tracks 28 are provided They tram cars are used to carry the lime to a dipping vat 29. 05 Track sections 28 which are alio'ned with the tracks 28 are provided. A car is lilled approximately one-third full'ot' lime from hopper or discharge chute 25 and runs on the tracks 28 and track sections 28. While 70 the car is standing on the sections 28. suit able lowering and elevating means are used to let the car with the lime therein down into the water in vat 29. The car is let't in the water in vat 29 long enough to wet the 75 lime thoroughly, approximately one minute is suflicient time. The lime is lowered into the water while the lime is hot. The cai is not water tight and the water readily enters the car and penetrates the linie. A 'fter 80 the car has remained in the water a sui'licient length of time, the car is elevated and run onto tracks fl() and then switched to storage track-portion 3l. The dippirucr ol the cars into the water (the water constantly flowing S5 into and out ot' the vat) causes or permits the linie to absorb water and the lime then fills the cars entirely by expansion The expansion of the hydration` lime, in the bulk confined in each car or walled container, fills the interstices between the lumps and disintegratint,r portions of lime while the walls of the container prevent lateral eX- pansion of the bulk and atthe same time exclude air from the upright sides of the bulk. These walls also prevent escape of the resultant gas th rough the lateral or up right sides of the hulk, so that these gases bulk for `assisting in its hydration. Since the hulk ma can not' spread laterally or downwardly, it rises to approximately three times its original height, thus increasingthe pressure upon parts of the hulk below its upper surface: The lime which rst hydrates, being;r lighter m5 than the lumps, is forced to the top of the bulk, and this aids the container in excluding air from the inner parts of the bulk. Therefore, much ot' the resultant tgras is not only detained in the hulk, but 4permanently u@ retained therein, thus not only assisting the hydrating process, but conserving the est" able chemical elements which tenti .to pass 0E and bolost in the :timos here. The oars of watered li'rne are loft on t 1o storago trado portion 31 about twenty-four hours for giving time for iinishng the hydration, enough tram oars 'afro provided for this purpose, the tracks 3lI being long enough to aocommodata tho necessary number or" oars.

- After the hydration is compietodyono car at er time is run from track-portion 31 over switch tracks 32 back to tracks 50 and. then on s ripple 33 so that tha contents of the our can be dumped into an elevator bin 34, rFilis bin is onarg'od towards theioottom lwhich 'is prog'etsd down into the ground. lime is relovatod by buckets 35 which are nttaohed to o, traveling belt 36 which runs on pull-sys 3i and This lime is thrown from tiebuckets down a. chut-o 39 into fr ,screen il By this system the hydrated linie is sspzrrzrted. from alf the cores :rnd the mpurtos and from evorythng Gratis not Hmosnc n. perfectly pure hydrate is all. that remains after the screwing oporston; The our@ lime is deivsred from the screen 29:0 into zr 'bin il and the imo is taken from nin il into a bagging machine 22 Whore the lime issarcked und pressed for commercial uses.
